2 Claims. (Cl. 128-92) My invention relates to the mechanical setting of fractured human limbs.

The objects of the invention are principally to secure better union of the fracture using mechanical manipulation; to prevent distortion which often results from fracture; and also to reduce the time required for complete healing of the fracture.

All the elements that comprise the wrap-around cylinder, block and finger are constructed of material through which the X-ray beam will pass unobstructed.

In the accompanying drawings,

Figure 1 is an end view of the mechanical finger block, showing a slight curvature to conform with the arm and leg at point of contact.

Figure 2 is a vertical sectional view of the mechanical finger block, bored to receive the mechanical finger shown in Figure 3.

Figure 3 is a vertical sectional view of the mechanical finger.

Figure 4 is an end view of the split wrap-around cylinder, showing the mechanical finger block with mechanical fingers attached thereto.

Figure 5 is a plan view of the split wrap-around cylinder, punched out at intervals to receive the mechanical finger block and also showing mechanical finger blocks attached thereto.

Referring more specifically to the drawings the nu meral 1 indicates the mechanical finger block housing, 2 the threaded bore into which the mechanical finger, Figure 3 is inserted.

2a is the hole through which the locking bolt, 9 affixes the mechanical finger block, Figure 2 to the split wraparound cylinder, Figures 4 and 5. g

3 shows the curvature of the mechanical finger block, Figure 1.

4 is the mechanical finger.

6 is the knobbed end of the mechanical finger which will revolve inside 5 the cushioned pressure button made of rubber or a similar substance.

7 is the split wrap-around cylinder.

8 indicates areas punched out at intervals which receive the mechanical finger blocks.

9 is the bolt which secures the mechanical finger block to the split wrap-around cylinder, Figures 4 and 5.

10 is the locking bolt nut.

11 is the hinge pin which secures the two halves of the split wrap-around cylinder together when it is inserted into the hinge joint 12 of the wrap-around cylinder.

Operation After inserting the hinge pin and locking the two halves of the split wrap-around cylinder around injured limb, the patient is then taken to the fluoroscopic or X-ray room and the point of fracture placed under the fluoroscope or X-ray machine. When satisfactory alignment has been attained through manipulation of the mechanical fingers, the fingers will remain in their respective positions. At this point the surgeon may, if he desires, apply a plaster cast. However, the mechanical fingers holding the fractured bones in position will necessarily hold the split wrap-around cylinder likewise in position.

I claim:

1. In a device for supporting fractured bones, a sleeve frame, at least two members hinged together to form said frame, a plurality of sets of fingers mounted in spaced relationship in said frame projecting radially through said frame, a mounting block for each set of fingers oriented in said frame to align the fingers of each set in an axial direction, means in said blocks for radially positioning said fingers and feet adjustably positioned on the inner ends of said fingers for applying pressure to said fractured bones by the radial positioning of said fingers.

2. A device as claimed in claim 1, having a cushioned pressure button on each of said fingers, each of said buttons being of greater dimension axially of the finger than the spacing between adjacent buttons.
